Extraction and concentration of high value metabolites from plant and animal waste
High value metabolites such astaxhantine, phycocyanobillin and phycoerythrines can be extracted from algae, fish processing residue or plant processing waste such as pomace. Such metabolites often have health promoting properties and can be used in the food industry as colorants or in the cosmetic industry as additives. The concentration and purification of such additives though require carefull low temperature processing in order to uptain the full benefit of the products. Further, the process need to be optimized from both a resource and economic point of view in order to give a sustainable production.
